Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516678, here are decompositions:

5 + 516673 = 516678
59 + 516619 = 516678
61 + 516617 = 516678
67 + 516611 = 516678
79 + 516599 = 516678
89 + 516589 = 516678
137 + 516541 = 516678
139 + 516539 = 516678

Showing the first eight; more decompositions exist.
